Gratings for high-load
Gratings for high-load are used for covering technological channels and platoforms, where are predicted the movement of vehicles and heavy wheeled mechanism.
They are produced as:
restistance welded type SP
we are producing by parameter 30×5, 40×5 until 80x5mm
pressed type P
we are producing by parameter 30×5, 40×5 until 110×5 mm.
Dimensioning of gratings for high-load according to norms DIN 1055 / 1072.
Main parameters for design this gratings are :
– wheeled pressure of vehicle by DIN 1072
– width between support of steel construction as table says:
To desinging gratings for high-load it is important to thinking also with dynamic load of gratings.
This is creating mainly in cases where the vehicle has in his driving path sections, which one are strained by braking force.
Then a wheel pressures of vehicles are multiplied by coeficient 1,4.
